The Iowa caucuses are six months away. Some Republicans worry Trump may be unstoppable

He's been indicted twice. Found liable for sexual abuse. And he's viewed unfavorably by about a third of his party. But six months before Republicans begin to choose their next presidential nominee, former President Donald Trump remains the race's dominant front-runner.

Early leaders don't always go on to win their party's nomination, but a growing sense of Trump's inevitability is raising alarms among some Republicans desperate for the party to move on. Some described a sense of panic -- or "DEFCON 1," as one put it -- as they scramble to try to derail Trump and change the trajectory of the race. But there's no clear plan or strategy on how to do that and Trump's detractors aren't rallying around a single alternative candidate yet.

"They're very concerned," former Maryland Gov. Larry Hogan said of fellow Republican leaders who share his view that renominating Trump would be a disaster for the party next November. "People expected us to have made more progress than we have at this point."

Hogan, who opted out of a campaign of his own in fear that an unwieldy Republican field would only benefit Trump, described a moment of realization that, "Oh my gosh, we really could have Trump as the nominee."

Polling finds Trump routinely besting his closest rival by 20 to 30 points or more. Of course, the six months that remain until the Iowa caucuses can be an eternity in politics, where races can turn in a matter of weeks or days.

And Trump faces glaring vulnerabilities, including state and federal investigations into his efforts to overturn the 2020 election and the possibility that he could end up in the unprecedented position of standing trial while simultaneously mounting a campaign.

But even critics acknowledge the outside events that many were counting on to dent Trump's standing -- namely his criminal indictments in New York and Florida -- have not hurt him. In fact, the charges led some voters who were entertaining an alternative to return to Trump's camp.
